Exposure pathways are the routes through which a hazard can enter the body. Ingestion occurs when contaminants are swallowed via food, drink, or hand-to-mouth transfer. Dermal contact happens when skin touches contaminated surfaces, water, soil, or chemicals, with some absorption through the skin possible. Inhalation is breathing in contaminated air, dust, vapors, or aerosols. Because all three routes are common ways hazards reach people, the option that includes all of them is the best choice. In practice, recognizing these pathways guides where to focus controls—handwashing and safe food/water practices to reduce ingestion, protective gloves and hygiene to limit dermal exposure, and ventilation or respiratory protection to curb inhalation exposure. Exposures can often involve more than one route at once, underscoring why multiple pathways are routinely considered in risk assessments.
